Abstract

We report results of measurements of optically modulated optical transmittance of GaAs doping superlattices. The data extend over a spectral region of 1.39-1.58 eV. We find that the peak transmission modulation reaches 21% for a 2.6-μm-thick sample and an optical pump power density of <10 W/cm² at room temperature. We interpret our data in the framework of a simple semiclassical model that includes the Franz-Keldysh effect both below and above the bulk GaAs band gap, as well as band filling and band shrinkage effects.
